We now pass some tests.

You can run "make check-gas" and we run some tests.
You need to have installed dejagnu.
We pass most of the tests so far....
Correct the info about DWARF debug info.
Remove EM_VIDEOCORE4 (It seems that we use EM_VIDEOCORE3)
Always check whether values fit into their reloc entries.

Change the name of the architecture (to more closely match how others arch's work).

This makes the binutils test suite pass.
Use a #define for the number of parameters (and increase it to 15)

This is needed for the more interesting vector instructions,
which all have a large number of parameteres.
Add a gas testsuite
Change comment characters (again).
Added two simple bne tests (these failed at some point).
